It means device is Region (RGCK) locked and has never been activated or Device has never been Activated if you get NCK + Defreeze.

So the country lock is active it will only be disabled as soon as its activated by a SIM from the country, which the Samsung phone, is purchased in/from.

That's why we are not getting the NCK, So please use the RGCK = Regional Unlock Code. Instructions are same: Insert SIM from another country, Power ON, Input the code next to RGCK and enjoy your factory unlocked Samsung.

If you have any issues with inputting the unlock code, please use our "How to" section for detailed unlock instructions.
